Siraitia grosvenorii sugar with improved sweetness and preparation method thereof

Abstract

The invention relates to siraitia grosvenorii sugar with improved sweetness and a preparation method of the siraitia grosvenorii sugar. The siraitia grosvenorii sugar comprises the following ingredients in percentage by mass: 0.1 to 2.1 wt precent of mogroside V, 0.02 to 0.40 wt precent of other triterpene glucosides, 10 to 50 wt percent of cane sugar / brown sugar and 48 to 89 wt percent of arabinose. The siraitia grosvenorii sugar is prepared by compounding siraitia grosvenorii high-power sweetening agent, cane sugar / brown sugar and arabinose; the siraitia grosvenorii high-power sweetening agent is prepared from mogroside as a raw material treated through sequentially passing through a polar macroporous adsorption resin column, a high-specific-surface-activity macroporous adsorption resin column and a small-hole reversed-phase gel column for physically refining; and the siraitia grosvenorii high-power sweetening agent is prepared from the following ingredients of 55 to 70 wt percent of mogroside V, 1.5 to 4 wt percent of mogroside IV, 3 to 10 wt percent of 11-O-mogroside V, 0.5 to 1.8 wt percent of siamenoside, 0.4 to 1.5 wt percent of mogroside VI, less than 0.2 wt percent of acid phenolic substances and less than 0.2 wt percent of pigment substances. According to a mogroside sugar substitute, the sweetness multiple is reduced, the sweet lasting time is shortened, the preparation taste is excellent, and the siraitia grosvenorii sugar is a sweet substitute easy to be accepted by consumers.

Description

technical field [0001] The invention relates to the technical field of plant extraction and separation and the field of sweetener compounding, in particular to a monk fructose with improved sweetness performance and a preparation method thereof. Background technique [0002] Mogroside is prepared from the fresh ripe fruit of Luo Han Guo, a plant of Cucurbitaceae, which is saccharified and then ripened, and then prepared through a series of separation and extraction steps. Among them, the most common commercially available mogroside is the V50 specification, and the content of mogroside V is around 50%. The main process is to prepare fresh Luo Han Guo through saccharification, ripening, crushing, water extraction, filtration, ceramic membrane microfiltration clarification, broad-spectrum macroporous adsorption resin chromatography, ion exchange resin decolorization, desalination, vacuum concentration, spray drying and other steps. have to. Mogroside has the best taste among...

AI Technical Summary

Problems solved by technology

[0012] In order to solve the defects of poor taste and taste properties of mogroside-based sweeteners in the prior art, the present invention proposes a method that utilizes the most common mogroside V50 on the market as a raw material and passes through a polar macroporous adsorption resin column. , high specific surface activity macroporous adsorption resin column, small pore reversed-phase gel column, activated carbon chromatography, and then add sucrose / brown sugar and arabinose for compounding, and finally prepare a kind of low sweetness (sweetness is sucrose / brown sugar 1-15 times), the taste is close to sucrose's monk fruit sugar
